They suggest regular cleaning will help keep performance on track. I am still skeptical, but I will do this and keep track of the system production monthly to see whether or not it's going to meet the guaranteed minimum production. I truly hope my solar system would performed as they claimed; I would be happy just to get the guaranteed minimum production. I updated my rating back to 5 Stars based on their cooperation in addressing the issues reasonably fair.

The estimate was detailed and easy to understand, and they took the time to answer my questions without rushing me or trying to upsell anything. What stood out most was their communication. They consistently called before arriving, showed up exactly when they said they would, and kept me informed every step of the way. That alone set them apart. It's rare these days to work with a company that actually does what they say they're going to do. The installation went smoothly and efficiently, and everything looks clean and professionally done. Pricing was excellent, especially compared to another solar company I had previously dealt with, and the overall experience was noticeably better. If you're looking for a solar company that is responsive, organized, and genuinely professional, I would absolutely recommend Aikyum Solar. It was a very positive experience from start to finish.

I was impressed with their customer…read moreservice, communication, and reputation, but we were not ready to proceed with installation at that time. A few months ago, we decided to move forward with installing a 13.4 KW solar system. Imperial Solar was fair and transparent during the evaluation, and efficient and detail-oriented throughout the installation. The crew arrived on time and left the area clean. The system was installed professionally and looks excellent. Since our meter change, our bill has decreased by 80%, even during winter. We look forward to seeing our savings in the summer. We are very satisfied with Imperial Solar and highly recommend them to anyone considering a solar installation.

I'd highly recommend Solar Optimum and Roofing Optimum…read more We've had our solar system from Solar Optimum for more than 10 years, and our experience is a great example of why choosing the right company from the beginning matters. They installed a high-quality system that has performed extremely well over the years. At one point, both of our inverters experienced a manufacturer-related issue. In fact, Solar Optimum identified the problem before we even realized something was wrong. They worked directly with the manufacturer to secure a replacement inverter at no cost and handled the installation quickly and professionally. When it came time to replace our roof, we didn't hesitate to reach out to Solar Optimum again. Their GAF Master Elite certification and the advantages of having the same company manage both the solar and roofing work provided tremendous peace of mind. The warranty benefits are excellent, and the roofing warranty is transferable, which adds real value and is something many roofing companies do not offer. We recently completed a full solar removal, reroof, and solar reinstallation project with the Optimum team, and we couldn't be happier with the outcome. The entire project was completed in about a week, exactly in line with the schedule that was provided at the start. The crews showed up on time, worked hard, communicated well, and cleaned up thoroughly at the end of each day despite the significant amount of work involved. From start to finish, the process was smooth, professional, and well-managed. It's rare to find a company that delivers this level of service over a relationship spanning more than a decade. We couldn't be more pleased and highly recommend Solar Optimum and Roofing Optimum.

I contacted Solar Optimum for a home backup battery installation using an Enphase 10C battery. They…read moreinitially quoted me $10,146.50 for the project. Before conducting a site inspection, they required me to sign a contract and pay a $500 deposit. After completing the site plan, they informed me that a panel upgrade was necessary and that the battery would need to be installed in an inconvenient location. These changes increased the project cost by an additional $3,700, bringing the total well above the original quote. I was surprised by such a significant price increase and decided to cancel the project. I then requested a refund of my $500 deposit. It took nearly two months and more than ten phone calls before I finally received an answer. At that point, I was told that the deposit was nonrefundable because I had signed the contract. I find it unreasonable that Solar Optimum required a signed contract and deposit before conducting a proper site assessment, then substantially increased the price afterward and refused to refund the deposit when I chose not to proceed. In my view, a thorough site inspection should have been completed before providing a quote and requiring a commitment from the customer. Based on my experience, I would advise potential customers to carefully review the contract terms and understand the refund policy before signing.

TL;DR: Rose is incredible. Honest, patient, actually knows solar and is not just a salesperson. She…read morewill answer every single question you may have and follows up. Has a professional installation crew and executes flawlessly and everything stays on track. Incredible follow-up and will not try to upsell you like other installers. If you're looking to install solar, you should absolutely go with OneSun. Give Rose a call to at least get a consultation and I'm sure your interaction will immediately stand out from other installers. Installing solar is something I kept putting off. When I found out that the tax credit would be going away at the end of 2025, I realized I couldn't put it off any longer. One of the reasons I kept waiting was how annoying solar reps were. Clearly just sales guys who didn't actually know anything about the equipment, technology, and process. I did a bit of research on local installers and OneSun came up a few times, all with nothing but great things to say and especially highlighted the installer's knowledge and patience. Before reaching out to OneSun, I informed myself as much as I could to the point that I knew what panels I wanted, size system, even what inverters I wanted installed. My first phone call with Rose immediately proved that all of the positive feedback I had read was for a reason. She took the time to actually listen to the specifics of my project, what I was looking for, and what questions I still had based on my research. She took the time to answer every question and even went into the technical details that I was interested in. It was clear that she was extremely familiar with not just the logistics, but also exactly how a solar system works as well as the technical details of all of the components in a system. She had my business after that first meeting but of course I still did my due diligence and got a quote from one other local installer which also had similar reviews. Although the sales rep was very nice, it was clear that he was just a sales rep and only reinforced why OneSun was the installer to go with. OneSun's pricing happened to be better but even if the other installer would have come in at a cheaper quote, I would have still chosen OneSun for the install. Rose started the permit process in July and made sure that everything stayed on track, especially since I wanted to make sure that the system be on before the end of the year in order to qualify for the tax credit. The timelines she provided were right on point and the install was scheduled for September. About a week before the install date, there was an unexpected problem. The panels that were originally planned for my install had gone completely out of stock. There had been some kind of manufacturing issue and those panel would not be coming back in stock for another couple of months which could push the project out to the following year. Rose let me know she could acquire slightly larger panels for the project and install it on schedule. I was about to ask what the additional cost for the larger panels would be, but before I was able to, she let me know that there would be no additional cost to me. I'm sure any other installer would have used the situation as leverage to add additional cost to the project. A testament to Rose's commitment to her customers. On installation day, the crew was professional and efficient. They completed everything in one day and made sure to keep everything as clean and organized as possible. Towards the end of the install, I had noticed that they ran one of the grounding wires out from the attic and down the face of the house where I had planned on completing another project in the near future. I knew that the wire would need to be redirected if it was left there so I asked the foreman if he could run it through a different path. Initially he felt like it would not be possible given the layout. I reached out to Rose just to make sure and see if she possibly had another solution. About 10 minutes later the foreman showed me another possible option which was much better for what I needed. It may have seemed like a small thing, but that was another instance in which I believe any other installer would have dismissed my request as pickiness and told me there was nothing else they could do. Rose took the time to speak with her foreman and truly assessed the situation to come up with a solution that fit my needs. It took LADWP about 6 weeks to get my meter installed and for my system to be turned on, but it was still well before the end of the year (and yes, I just got my tax refund with that hefty solar tax credit). It's rare to come across someone like Rose who is honest, patient, and who truly has her customer's best interest at heart. Combine that with impeccable execution and communication, and there is no one else I would recommend for a solar install project. In fact, my parents are considering a small project and I've already told them about Rose/OneSun.

When I first contemplated getting solar panels for our house, the entire process looked daunting. I…read moredidn't know anything about the technology or equipment and I felt ill prepared to make any decisions about what our house needed. There are so many companies out there, it's hard to know who to trust. As soon as I did a few online searches, I was flooded with emails and texts from multiple companies with high pressure sales pitches. One company charged me $350 to do a site survey, just to get a quote for the project, then came back with a revised quote adding $7000 to dig a trench for electrical wiring due to "the location" of our electrical panel. I found OneSun on a yelp search and as soon as I spoke with Rose Avakian, I knew my search was over. This company stands out from the others. There was no sales pitch, pressure, or upsell. Rose explained the technology and equipment in a way that made it understandable and approachable. When her team came to look at our place, they found no need to dig a trench and simply connected to our existing electrical panel. Had they needed to dig a trench, the price they quoted was nowhere near $7000.  From start to finish, the entire experience was transparent, seamless, professional and expedient. The attention to detail and care the team put into making sure everything was done right far exceeded my expectations. If you're looking to go solar, look no further than Rose and OneSun. This is truly the best company I've ever worked with!

I couldn't be happier with OC Solar! From start to finish, their team was professional,…read moreknowledgeable, and truly committed to finding the best solution for my home. They installed a complete solar system that's already making a noticeable difference in my energy bills. Even better, they set me up with backup batteries so I have peace of mind knowing I'll have power when I need it most. And the locked-in rate they secured for me? That's going to save me money for years to come. The installation crew was efficient and respectful of my property, and the whole process was much smoother than I expected. OC Solar made going solar easy and stress-free. If you're considering solar, I highly recommend OC Solar. They deliver quality work, excellent customer service, and real value. Five stars all the way!

This has been an unnecessarily difficult process. Communication has been non-existent. I have…read morebeen handed off to various people every time I called trying to get information. They do a lot via text, which I liked, but it turned out not at all useful. I would text for updates, and hear nothing back. I would call to find out my contact was out of the office, on vacation, or any number of excuses. This went on for many weeks. I did not know the date for installation until a delivery of equipment showed up at my house unannounced. It was a good thing I happened to be home that day! I thought the installation itself had gone well. They installed the system in two days and everything looked great. Then, I had to wait for the meter collar to be installed. I was told it was going to be performed by their technician. Turns out it has to be done by SCE and that had not been scheduled. After I called again, SCE was finally notified. SCE arrived several days later to discover the cables were too short to install the meter. Now I have wait again for OC solar to come out again and fix this issue and wait again for SCE to finally install the meter so that I can use my new system. I hope the system works.

I searched on Yelp, needing to find the right company to do the upgrade without an unnecessary upsell. Carlos reached out to me right away and took the time to listen and explain the options.

Carlos' company provided the panels. Btw, Anca Solar's pricing was very reasonable and within my budget. I scheduled the service and the guys were great, even arriving early. They got the job done in one day and the system works great! The biggest plus is, Carlos responded to my emails very quickly, keeping the line of communication open.
